Vascutek Limited, a world leader in the development of vascular grafts, has combined their latest technological developments in polyester textile technology with unique endovascular design features to produce Anaconda™, the world's next generation of AAA stent graft systems. Intuitive and of a modular design, Anaconda™ is the only repositionable device which also features exceptional flexibility. The modular design comprises bifurcate bodies, iliac legs and aortic cuffs. Nitinol, an alloy of nickel and titanium, has self-expanding properties and forms the top "ring-stent" of the bifurcate body section. The "ring stent" is composed of multiple turns of Nitinol wire that provides significantly increased "hoop-strength" enabling a conformable and secure haemostatic seal against the vessel wall to be achieved. Nitinol hooks located adjacent to the "ring stent" anchor the graft in position thus preventing graft migration. The iliac limbs are fully supported with Nitinol and the bifurcate bodies feature a distal contra-lateral lumen Nitinol support, which in conjunction with a unique intrinsic magnet guidewire system facilitates cannulation of the bifurcate section.
